Was just thinking the other day about how much I miss Kaitai Dismantlement puzzles. Happy to see a new one! Thanks for finding and posting this puzzle, Bart. Hopefully, there will be more of these in the future.

I was kind of sad when it looked like Dismantlement was over---it was one of my favorite series, too. But if this is what they're going to look like from now on, it might be better if we don't get another one. Terribly simple.

Well with all these previous comments I don't dare to say, but I agree with all, except for the explosion puzzle. I guess I am blind as by the sound of the comments the answer should be right in my face.

I have been guessing that the last character is an L, but the ones before have several options: H K M or N and C E or Z.
